what is the out group of this cladogram
Answer:ur answer is protozoa
Explanation:
In cladistics or phylogenetics, an outgroup is a more distantly related group of organisms that serves as a reference group when determining the evolutionary relationships of the ingroup, the set of organisms under study, and is distinct from sociological outgroups.
The out group in this cladogram is protozoa that is distantly related to the other organism s in the given cladogram.
The out group is a creature that is only distantly connected to the other creatures on the cladogram. The out group, which is commonly assumed to represent the ancestral situation from which the organisms in the cladogram later evolved, contributes to the tree's roots.
The organisms in the in-group are connected to one another. The cladogram is founded on the introduction of a distantly related creature known as the out group. The out group is frequently represented by a single branch on the cladogram.
Out group is an evolutionary phrase that refers to a taxon or lineage that is not part of the taxon group being examined.
Thus, the out group in this cladogram is protozoa.

Carbon monoxide (c.) is the gas that makes up the majority of air pollutants.
What is carbon mono oxide?
Carbon monoxide (CO) is a colorless, odorless, and tasteless gas that is produced by the incomplete combustion of carbon-containing fuels, such as gasoline, natural gas, coal, and wood. It is a highly toxic gas and can be harmful to both humans and animals.
When inhaled, carbon monoxide enters the bloodstream and binds to hemoglobin, the molecule responsible for carrying oxygen to body tissues. This binding affinity is much stronger than that of oxygen, resulting in reduced oxygen delivery to organs and tissues. As a result, exposure to high levels of carbon monoxide can lead to symptoms such as headache, dizziness, nausea, confusion, and in severe cases, loss of consciousness and death.
Carbon monoxide is a significant air pollutant, often found in areas with heavy traffic, industrial emissions, and improper ventilation. It is important to have proper ventilation systems and to use carbon monoxide detectors to minimize the risk of exposure to this dangerous gas.

Why is it that duck-billed platypus is classified as a mammal
Answer:
The platypus is classed as a mammal because it has fur and feeds its young with milk. It flaps a beaver-like tail. But it also has bird and reptile features — a duck-like bill and webbed feet, and lives mostly underwater. Males have venom-filled spurs on their heels.
*ANSWER PLEASE TY* In some cases, water shortage is caused by lack of shade resulting in ponds drying up. What human activity causes this? a.) air pollution b.) water pollution c.) deforestation
Answer:
c.) deforestation
Explanation:
"Lack of shade" means that the ponds no longer have enough coverage over them such that the sun shines strong above the river causing it to dry up. Trees are mostly huge tall and are very likely to provide shade for the river originally, and since deforestation means the mass cutting down of trees, the answer is c.

A standard incandescent light burns through 50 watts of electricity per hour. Replacing an incandescent bulb with an LED bulb can save 6 tons of household emissions per year. Saving 6 tons of carbon emissions is the same as reducing your gas consumption by 700 gallons. (proving b wrong)
you can help reduce your carbon footprint and other greenhouse gases by using energy-efficient home appliances since they have lower emissions of harmful gases into the environment. (proving c wrong)
Many farmers and gardeners compost their plant and animal waste. The living material naturally decays in compost bins, forming a dirt-like substance that’s rich in nutrients. The next season, farmers use this substance as a natural fertilizer for their crops. A biology student has grown tomato plants for several years. Until now, he used an artificial fertilizer formulated for tomato plants. This fertilizer caused his plants to grow faster and taller than they grew in unfertilized soil. The student wants to know whether using natural compost will cause his tomato plants to grow faster and taller than his artificial fertilizer. How does the design of your experiment control for outside factors that may affect the results?
Answer:
yes the fertile soil will grow faster and taller
Explanation:
the fertile soil will grow faster because it has what the plant needs

Hyponatremia is a condition in which the sodium in the blood is too low. Uncontrolled spasms, which are sudden, involuntary contractions of muscles, are among the symptoms of hyponatremia. Why do they occur?
A.
Sodium is needed to generate an action potential.
B.
Sodium makes up most of the myelin sheath.
C.
Sodium is the signaling molecule that transmits impulses across a synapse.
D.
Sodium controls voluntary movement, and potassium controls involuntary movement.

Answer:
Option A. Sodium is needed to generate an action potential.
Explanation:
Action potentials are generated by the special types of the voltage-gated channels which are embedded in the plasma membrane of the cell.
These channels are shut when the membrane potential is near zero and the voltage-gated channels open only when the membrane potential is more than the threshold voltage.
When the channels are open then they allow the flow of sodium ions which ultimately changes the electrochemical gradient which rises the membrane potential. This rise in membrane potential generates the action potential.

Answer:
1. Latitude. Kuala Lumpur is located in the equatorial zone, near the equator, so it receives a lot of sun for the entire year, and this explains its warm climate.
2. The main reason for this difference is the altitude: while Minsk is located at 280 meters over the sea level, Banff is located at approximately 1400 meters over the sea level. As the altitude is higher, the average temperature is lower.
3. Jakarta: in fact, it is located at a similar altitude of Kuala Lumpur (just in the opposite hemisphere), in the equatorial zone, while Baltimore is located much more north, so in a colder region.
4. Because they are located at approximately same latitude (just in the opposite hemisphere), so they are more or less same distance from the equator, and they receive more or less same amount of sun light, therefore they have similar climate.

Up until now, no characteristics or qualities have been assigned to the predators and prey. Suggest a trait of the prey and a trait of the predators that might account for the results of your model. How do the results of your model help explain the process of natural selection in a predator-prey relationship?
Answer:
Predator foraging traits include;
body size (mass or length), gape size, hunting or foraging mode (for example, ambush or active hunting), and feeding mode (for example, chewing or suctorial) .Prey vulnerability traits include;
body size (length and mass), body shape, defense (for example, physical or chemical protection), ability to avoid detection (crypsis or camouflage), mobility, ability to recognize and detect predators, and evasive or escape behavior (which can be elicited by physiological trait responses.But whether or not predators engage with prey, or prey respond to predators in the first place, depends fundamentally on their relative body sizes (or predator gape and prey body shape). Pursuing prey that are too large or cumbersome can be harmful or energetically costly to predators, and pursuing prey that are too small may not be worth the energetic return.
As these populations continue to reproduce over time, the actions of natural selection can also change the species to make them better predators, or more defensive prey. Either way, this adaptation changes the entire predator prey dynamic. If one species cannot then adapt an appropriate defense, they may go extinct.
